My linear motion ball bearing slide block did not come with this little knob. I don't know what it's called. I need to purchase a replacement for mine but I don't know the name. This side hole here is used to be grease in there, I think.
It's a grease fitting, sometimes called a Zerk fitting. Available at any auto parts store.
Take the bearing block with you if you can to make sure the threads are correct.
If your bearing is going to get a lot of use or is in a dirty environment, you may also want a grease gun and the appropriate kind of grease. For light use, maybe you'll never need it.
I did a Google image search and found it to be a 'pillow block' ..
"What is pillow block used for?
Pillow block bearings are actually housings that have a bearing fitted into them. They are usually mounted in cleaner environments and are not meant to bear higher loads. The main application is to mount bearings safely with a stationary outer ring and a rotating inner ring.Oct. 6, 2016"

Be careful getting a grease fitting from your auto parts store. Most/all linear slide blocks like yours are imported and most have metric everything. If it's ANSI fitting it's likely either 1/4"-28 (straight thread) or 1/8" NPT (tapered thread). If it's metric you could have a BPSP or M6, M8 or M10...
You caught my mistake. It was supposed to be BSPT (British Standard Pipe Taper) which more common in Asia. It looks similar NPT but has a different thread pitch and different thread angle.
Can anyone tell me what these might be? Found them in the back of a drawer.

I have a couple of screws on an exterior light that have been exposed to the elements for years. The light needs to be replaced so I wanted to unscrew the exterior plate. But the screw head is damaged. I tried using a phillips head but that didn't work. Based on advice on the web I tried using a flat head, but that just made matters worse. Any suggestions here? I don't have any tools other than the basic manual screwdrivers but I can go and grab something from HomeDepot if necessary. Please advice!
